, Be itknown that I, BERNHARD WAGNER,

merchant, a subject of the King of Prussia,-

residing at No. 99 .Kaiser Wilhelmstrasse, Stettin, German Empire, have inventednew and useful Improvements in 'Ap aratus for Coking Briquets, of which the following is a In my United States atent application, Serial No. 243,948, dated February 3, 1905, Patent No. 829,448, August 28, 1906, I have disclosed certain apparatus for-rendering socalled brickffuel or briquets weatherproof by coking the binding agent, which is soluble in water, used inthe manufacture thereof. According to the invention the briquets are conducted through an inclined rotary drum communicating at one end with a furnace and at the other end with a smokechamber, and this drum automatically turns the briquets. andfeeds them forward in such manner that the briquetscharged into the drum when delivered therefrom are weatherproof.

My present invention relates to improvements in a paratus-of the kind referred to in which the briquets instead of being exposed to the direct action of the furnacegases, as described in the said patent applica tion, are heated indirectly, the furnace-gases actin up the outerv walls of the various cham ers. f=.f 1heheatin'ggases may, as de-' scribed in the said patent, pass through the apparatus either in the same direction as the,

briquets or in a direction contrar thereto. Furthermore, the gases. after t ey fha've heated the briquets by indirect action may be caused to act directly thereu on, or,'vice versa, they may first act direct y and thenindirectly on the briquets', depending upon the nature of the com osition of the material from which the briquets are made. 1

.My invention is illustrated in the accompanying drawings, in which- Figure 1 is a diagrammatic longitudinal section of a drum having six coking-chamhers, together with feed-hopper. Fig. 2 is a cross-section on the line a: a: of Fig. 1. Fig. 3. is a cross-section on the line y .y of Fig. 1. Fig. 4 is an elevation of a complete'plant embodying the, coking-drum shown 111 Fignkl 1 e drawn to a reduce scale. Fi a view of a similar plant, but so eslgned that the furnace-gases pass in contrary direction Patented April 9, 1907.

to that of travel ofth'e brique'ts. Fig. 6 is a diagrammatic fragmentary longitudinal section of a drum having two groups of cokingchambers, together with feed-ho per. Fig. 7 is a cross-section through this rum. Fig. 8 is a fragmentary longitudinal section of a complete lant embodying the drum shown in Fig. 6 d i'awn to a reduced scale. Fig.9 is a like view of a similar plant, but of such design that the furnace-gases pass in a contrary direction to that of travel of the briquets. plant of such construction that the furnacegases act both indirectly and directly on the' briquets. Fig. 11 is a like view of'a plant differing from that shown in Fig. 10, inasmuch as the furnace-gases first'pass through the central chamber the same direction as that in which the briquets travel in'the coking-chambers. Fig. '12 is a like view of a giant in which the furnace-gases first act ectlyand then indirectly on the bri uets. 13 is a diagrammatic fragmentary e evation and part section of a drum the cokingchambers of which are fitted with screwblades. Fig 14 is a cross-section on the line 2 z of Fig. 13. Fig. 15 is a longitudinal section of a fragment of a coking-chamber providied with a screw-blade drawn to alarger sea e. A

Referring more particularly to the form of apparatus shown in Figs. 1-4, the heatlnggases from the furnace 17 pass through the smoke-chamber 18 in the same direction as the briquets travel through the apparatus, so that these gases act upon; the walls of the chambers 1 containin "the briquets, and

thus heat; the latter. or the purpose of preventing the access of the furnace-gases to the coking-chambers 1% of the drum the lat-1 ter are closed at the furnace end by a-stafar that tligii'nrnace-gases pass through the 6'5 Fig. 10 is a longitudinal section of a A central chamber 1 of the drum 1 to the central drum-chamber 1 in a direction contrary' to that in which the briquets travel through the coking-chambers 1.

The construction shown in Figs. 1 to 5, in-

elusive, consists of two concentric cylinders or tubes, the space between the two cylin v ders'or tuhesheing divided longitudinally by transverse. partitions into any desired number 'of compartments, six compartments besuitable well-known means ing shown Fig. 2.' These partitions may be perforated. or unperforated, so that the vanous com .artments may or may not communicate. t eretlu'ough.- These cylinders are supported in any well-known way and by any well-known means, whereby a rotary motioiimay be imparted to said cylinders by With the apparatus shown 6 and 7 the walls of two or'more groups of coking-Y chambers can be heated simultaneously by the furnace-gases. In Fig. 8 such an appar" ratusis shown in which the; heating-gases [flow in the same direction as that in which "the. briquets travel; in Fig. 9 the gases and briquets travel inopposite directions. The construction shown in Figs. 6 to 9, 1n-

' elusive, is composed ofa series of cylinders I concentric to each other, in the present inf stance five cylinders being shown. These cylinders are so constructed and arranged that alternating chambers are formed for the passage of the heating-gas and the assage of furnace-gases first pass throughthe central the briquets' to .be treated. are provided for supporting and rotating the same, as described abovesin connection with Figs. lto 5. I

The furnaces-gases instead of only acting indirectly may also exert a direct action. They may act first indirectly on the briquets and then directly, or vice versa.

In the apparatus illustrated in Fig. 10 the chamber 1" in the opposite direction to that of travelof the bnquets and then flow through the coking-chambers 1 in the same direction as that in which the bri uets travel, escaping finally through a pipe 1 to the atme here. In the apparatus shown in F 11 t e arrangement is similar, but reve The furnace gasesl'first pass through the chamber 1 in the direction of travel of the bl'iq uets and then return in the contrary directlbn through the coking-chambers 1.

With these constructions of the apparatus also several groups of chambers may naturally be heated simultaneously, if desired.

If the brigu'ets areto be heated first direct and then 1ndirect,- an apparatus such as shown 12 may be used. The'fur gases here pass first throu h the cokingchambers 1 in the contrary irection to'that in which the briquets travel and then return through the central chamber 1 in the same directronas that in which the briquets move.

. The construction of cylinder shown in 10130 12, inclusive, is substantially the same as that shown :and described in connection with 1- to 5 and would" need no descriptionhere. 'In all ,of the con- ,structions shown suitable means, such as hoppers, are provided for charging the cylin- Suit'a le means 1 ders. with briquets,.aiid suitable discharge imeans'and receptacles are provided for receiving the coked briquets.

Th'e-coking-chambers of the inclined ro-- tating feeding the briquets automatically from the top to the bottom end may be advantageously arranged in such manner that premature exit of .the bri uets from' the coldngmasing' is prevented t at is to say, means may be provided'whlch insure of all mg agent; Figs. 13-1-5 show an apparat-us constructed in this manner. The 1nthe briquets alike being exposed to the ac ti-on of the furnace-gases for'such uniform period as is necessary for-coking of the hindnerwalls of the coking-chambers 1 are pro- 'vided with screw-blades 22, which, as Fig. 15 shows, cross'the train of briquets, and thus constitute partitions, retarding the free advance of the row of briquets, to a certain extent without, however, actually obstructing the proper feed and regular of the briquets. In this way guarantee is offered I for each individual briquet remaining the same length of time in'the coking-casing,

so that-each briquet is submitted to the same coking process both as regards duration and the action of the furnace-gases, whereby also guarantee is given that each briquet which leaves the coking-drum is actually weatherproof. Instead of continuous screw-blades merely parts or sections of such blades may be provided inany suitable manner. The blades may also be perforated, if desired,in order that uniform 'action'of the furnacegases feredwith.

Having thus described my invention, I claim as new 1. In apparatus for treating briquets, an
